What brand are you drinking?
You learn something new everyday, I have never heard of Pu Erh as a red tea. Red tea has always been Rooibos in the stores I have shopped at.

At first I thought you were talking about red label Pu Erh and was going to be jealous. One references a specific pu erh from 1955 that sells for an insane amount of money.
